How to bookmark all open tabs in Firefox

2012-01-26T14:20:00.002Z

Press Ctrl+Shift+D or go to Bookmarks and select "Bookmark all Tabs". This will save all the open tabs into one folder and you can resume surfing the next day by select "Open All in Tabs" from the bookmark folder.

Bonus Tip: Name this folder something like "Feb25" or "022508" so it becomes easy for you to guess the date from the folder name itself.

Convert Bluray to DVD

2012-01-21T17:31:00.000Z

Bluray discs are becoming the norm for digital video, leaving DVD behind. But there are still many occasions where only a DVD player is available. One solution is to buy both the BD and DVD versions of a movie, and there are bundles that sell both versions at discount pricing.

However, if you want to convert an existing Blu-ray disc, you will need special software:
- AnyDVD HD - required to bypass the Bluray protections, and to "rip" the movie to a disc image. Works very well.
- DVDFab Bluray to DVD - a good option to make the conversion. It allows you to select the main title to convert, along with the audio and subtitles to keep.
- VSO Bluray to DVD - similar to the previous. Trial version converts only the first 10 minutes, so that makes me recommend DVDFab instead.

The end solution works but has some drawbacks:
- Relatively long conversion times: ~1 hour for ripping, ~1 hour for converting, ~1/2 hour for burning
- Subtitles fonts become pixelated.
- Price tag: ~ EUR 100.

Essential Disc Tools

2012-01-15T23:38:00.001Z

To avoid burning some discs - CDs, DVDs, Blurays, ... - it is always handy to use disc images. There are several file formats for disc images but the most widely used is the ISO image format.

There are two essential - and free - disc image tools that I recommend:
- WinCDEmu - mounts disc images to any free drive letter
- ImgBurn - creates ISO files from disc directories and burns image files to discs

How to convert Excel tables to LaTeX

2011-12-16T11:18:00.000Z

Ernest 10.22.09 at 09:38

I just installed excel2latex to Excel 2007. Just put the ‘.xla’ file in any folder preferably the add-in folder under “C:\Documents and Settings\\Application Data\Microsoft\AddIns\” then open up Excel > Office Button > Excel Options > Add-ins > Go and select it from the menu that appears, or browse to the folder where you put it. That should give you a button under Add-ins in Excel which works fine. At least it works for me. I am running Win XP.

Nano technology joins the battle against counterfeiting

2011-12-14T19:09:00.000Z

Imagine a bill covered with microscopic holes that make it glow slightly in the light. It's tech borrowed from a butterfly, and it may soon be foiling counterfeiters around the world.

(...)

The technology was inspired by the Blue Morpho butterfly, whose brilliant blue coloration comes not from pigment but the way that tiny holes in its scales reflect light. But the tech, called Nano-Optic Technology for Enhanced Security (NOtES), is different from the Morpho butterfly's wings, and pretty much all other bio-inspired reflective optical technologies, in that it is both extraordinarily thin and functions even in dim light.

NOtES exploits an obscure area of physics to accomplish its bright and sharp display, known as plasmonics. Light waves interact with the array of nano-scale holes on a NOtES display--which are typically 100-200 nanometers in diameter--in a way that creates what are called "surface plasmons." In the words of the company, this means light "[collects] on the films surface and creates higher than expected optical outputs by creating an electromagnetic field, called surface plasmonic resonance."

Sovereign Keys to strengthen Public Key Infrastructure

2011-11-24T23:08:00.000Z

The Electronic Frontier Foundation (EFF) is proposing an extension to the current SSL chain of trust that aims to improve the security of HTTPS and other secure communication protocols.

EFF's "Sovereign Keys" (SK) specification is designed to put the control give domain owners control over the link between their domain names and their certificates after recent Certificate Authority (CA) compromises raised serious questions about the security of the entire Internet Public Key Infrastructure (PKI).

One of the main problems with the current PKI model is the lack of control over CAs and their subsidiaries. There are literally hundreds of organizations spread around the world that are allowed to issue certificates for any domain name and some of them are operated by governments that practice Internet surveillance and censorship.

Sovereign Keys was designed to solve this problem by allowing domain owners to sign CA-issued certificates with their own private keys for additional authenticity. These validated domain-certificate associations are kept on so-called timeline servers and are synchronized with mirrors that are queried by clients.

How About Better Parents?

2011-11-21T17:23:00.000Z

In recent years, we’ve been treated to reams of op-ed articles about how we need better teachers in our public schools and, if only the teachers’ unions would go away, our kids would score like Singapore’s on the big international tests. There’s no question that a great teacher can make a huge difference in a student’s achievement, and we need to recruit, train and reward more such teachers. But here’s what some new studies are also showing: We need better parents. Parents more focused on their children’s education can also make a huge difference in a student’s achievement.

Computer Programming for Children

2011-11-17T00:13:00.000Z

New and more sophisticated tools are changing the way that the next generation learns to program computers. Children can now create elaborate scenes and games without the cryptic commands that were once the only way to tell computers what to do. The most talented children can also use some of the sophisticated tools normally used by professional programmers, because the tools are now often easy enough for someone to pick up with only a few months of study.

Tony Blair's 10 dos and don'ts for religion and democracy

2011-11-11T19:07:00.000Z

Tony Blair, CNN.com Belief Blog, 2011-11-11

1. DO have democracy-friendly religion and religion-friendly democracies.

2. DON’T think you understand democracy if you think it’s only about elections: it’s about a culture and mindset which includes freedom of thought, freedom of expression, political and religious pluralism, and human rights.

3. DO maintain equality of treatment for different religions within the law as a core element of the secular state.

4. DON’T duck difficult conflicts involving religious and secular ideas: discuss them openly.

5. DON’T rush to legislation to solve religious conflict; instead seek first to resolve it by discussion and accommodations.

6. DON’T allow religious schools to opt out of the same national standards and core curriculum that you expect of everyone else.

7. DO listen to religious voices on social, political and economic issues, and allow people to justify their views on explicitly religious grounds if they want.

8. DO insist on religious leaders making their case by reasoned argument not by bald assertion or authoritarian claims. Insist on that for atheists and secular leaders too.

9. DO NOT allow religious voices to have dominance in the public sphere if they cannot achieve majority support through democratic means.

10. DO ensure, whether the overwhelming democratic choice is either an atheist state or one dominant religion, that the voices of religious minorities and those who have no faith are protected.

Remember that none of us are qualified to state with certainty the will of God – so humility, openness to others, and interfaith dialogue are all essential for a healthy society.

Tackling a test in an infinite loop

2011-11-03T10:29:00.001Z

I had a bug that was causing a unit test to go in an infinite loop. Gradle would not print any output from the test because the standard output stream is captured to a test report.

To debug I used the following two techniques:

1 - I accessed the actual standard output, bypassing Gradle's redirection for this specific situation (this is usually not a good idea):

    PrintStream actualStdout = new PrintStream(
        new FileOutputStream(FileDescriptor.out))
    actualStdout.println("test message")

2 - I placed a pause inside the loop that was not stopping to be able to read the messages and make sense of them in human timescale (1000 milliseconds = 1 second).

    Thread.sleep(1000)

Gradle flatDir repository

2011-11-03T10:22:00.001Z

Q:
"
For a Gradle flatDir repository, is it looking for a local filesystem that is built up like Maven (pom's etc)..
or is it just looking for jar files in a folder called lib?
"

repositories {
flatDir name: 'localRepository', dirs: 'lib'
}

A:
"
As you assume it just looks for jars/wars/whatever in the 'lib' folder. It resolves versions by looking at the version number in the filename. for instance:
myveryownjar-1.2.0.jar
spring-2.5.6.jar
"

"
Pretty much. For each dependency that you declare in the build script, Gradle will look for a corresponding file in the 'lib' directory. For example, for a dependency on 'junit:junit:4.7', Gradle would look for
lib/junit-4.7.jar or lib/junit.jar. It assumes there are no transitive dependencies.
"

Researchers crack XML Encryption

2011-10-24T10:40:00.000Z

German researchers have demonstrated a technique for breaking the encryption widely used to secure data in online transactions, which they say “poses a serious and truly practical security threat on all currently used implementations of XML Encryption.”

The attack is able to recover 160 bytes of plain-text message in 10 seconds and decrypt larger amounts of data at the same pace, the researchers said.

Although the attack, described in a paper delivered last week at the ACM Conference on Computer and Communications Security in Chicago, was directed against the XML Encryption standard, it exploits weaknesses in the cipher-block chaining (CBC) mode of operation that is commonly used with many cryptographic algorithms. This makes it likely it could be used against non-XML implementations as well.

Red Herring

2011-10-04T10:53:00.002Z

Red herring is an idiomatic expression referring to the rhetorical or literary tactic of diverting attention away from an item of significance. For example, in mystery fiction, where the identity of a criminal is being sought, an innocent party may be purposefully cast in a guilty light by the author through the employment of deceptive clues, false emphasis, "loaded" words or other descriptive tricks of the trade. The reader's suspicions are thus misdirected, allowing the true culprit to go (temporarily at least) undetected. A false protagonist is another example of a red herring.

Screen capture

2011-09-23T11:08:00.003Z

Screen captures are useful for most computer users. You might need to show a screen to someone for help, or to include a computer screen in a report, or just to keep a hard record of something you saw in your computer.

In Windows you can capture the screen using the "Print Screen" key. Just press it and then you can paste the image into any program capable of handling graphics. Also, if you want to capture just the active window, use "Alt" + "Print Screen".

If you want to automate the screen capture task or have additional control, I strongly recommend the Greenshot tool. It's very simple and very effective. And it's also open-source and free!

Also, since Vista, Windows also includes a snipping tool.

To complete the topic of screen capture, I also use the ScreenGrab Firefox extension. It's especially useful if you want to capture a complete web page, without having to scroll the window.

Relation vs Relationship

2011-09-22T14:47:00.000Z

When should you use "relation" and when should you use "relationship" ?

A relationship is a close friendship between two people, especially one involving romantic feelings.
Relationship can be used in two other ways. It can describe two things and the way in which they are connected.
It can also describe close ties between people or groups of people and the way they feel and behave towards each other.

Relation also describes the link between people, groups or countries and the way they behave towards each other. In this sense there is very little difference between relations and relationship.
Most of the differences are context specific in this sense. For example, we talk about diplomatic relations and race relations, not diplomatic relationships or race relationships.
Your relations are also members of your family. Your blood relations are the people who are related to you by birth, not through marriage. If you say that they are your own flesh and blood, you are emphasizing that they are members of your own family.

Internet's memory effects quantified in computer study

2011-08-11T07:22:00.001Z

Psychology experiments showed that people presented with difficult questions began to think of computers.

When participants knew that facts would be available on a computer later, they had poor recall of answers but enhanced recall of where they were stored.

The researchers say the internet acts as a "transactive memory" that we depend upon to remember for us.

Lead author Betsy Sparrow of Columbia University said that transactive memory "is an idea that there are external memory sources - really storage places that exist in other people".

The idea being, that because such servers generate so much heat, why not use them to heat homes, instead of wasting even more energy by cooling the air in centralized locations.

The Glorious Folly

2011-08-09T22:57:00.000Z

The Glorious Folly by Louis de Wohl

This book is a sequel to The Spear and it covers the time span of the life of Saul of Tarsus a.k.a. Saint Paul. Despite this, St. Paul is not the main character in the book, Cassius Longinus is. The book is a good read, but not so good as The Spear .

Sometimes we think if we lived in the time of Jesus it would be so much easier to believe in Him. However, from De Wohls' depiction of the period, it is clear to me that faith and freedom play the same crucial role as today.

Cornell computers spot 'opinion spam'

2011-08-09T07:22:00.007Z

If you read online reviews before purchasing a product or service, you may not always be reading the truth. Review sites are becoming targets for "opinion spam" -- phony positive reviews created by sellers to help sell their products, or negative reviews meant to downgrade competitors.

The bad news: Human beings are lousy at identifying deceptive reviews. The good news: Cornell researchers are developing computer software that's pretty good at it. In a test on 800 reviews of Chicago hotels, a computer was able to pick out deceptive reviews with almost 90 percent accuracy. In the process, the researchers discovered an intriguing correspondence between the linguistic structure of deceptive reviews and fiction writing.

Robots Threaten Jobs

2011-08-08T07:22:00.000Z

Amid all the job losses of the Great Recession, there is one category of worker that the economic disruption has been good for: nonhumans.

From self-service checkout lines at the supermarket to industrial robots armed with saws and taught to carve up animal carcasses in slaughter-houses, these ever-more-intelligent machines are now not just assisting workers but actually kicking them out of their jobs.

Automation isn’t just affecting factory workers, either. Some law firms now use artificial intelligence software to scan and read mountains of legal documents, work that previously was performed by highly paid human lawyers.

Computer learns language by playing games

2011-07-15T07:22:00.000Z

In 2009, at the annual meeting of the Association for Computational Linguistics (ACL), researchers in the lab of Regina Barzilay, associate professor of computer science and electrical engineering, took the best-paper award for a system that generated scripts for installing a piece of software on a Windows computer by reviewing instructions posted on Microsoft’s help site. At this year’s ACL meeting, Barzilay, her graduate student S. R. K. Branavan and David Silver of University College London applied a similar approach to a more complicated problem: learning to play “Civilization,” a computer game in which the player guides the development of a city into an empire across centuries of human history. When the researchers augmented a machine-learning system so that it could use a player’s manual to guide the development of a game-playing strategy, its rate of victory jumped from 46 percent to 79 percent.

Air Power

2011-07-13T07:22:00.000Z

Researchers have discovered a way to capture and harness energy transmitted by such sources as radio and television transmitters, cell phone networks and satellite communications systems. By scavenging this ambient energy from the air around us, the technique could provide a new way to power networks of wireless sensors, microprocessors and communications chips.

“There is a large amount of electromagnetic energy all around us, but nobody has been able to tap into it,” said Manos Tentzeris, a professor in the Georgia Tech School of Electrical and Computer Engineering who is leading the research. “We are using an ultra-wideband antenna that lets us exploit a variety of signals in different frequency ranges, giving us greatly increased power-gathering capability.”

Improving recommendation systems

2011-07-12T07:22:00.004Z

Devavrat Shah, the Jamieson Career Development Associate Professor of Electrical Engineering and Computer Science in MIT’s Laboratory of Information and Decisions Systems, thinks that the most common approach to recommendation systems is fundamentally flawed. Shah believes that, instead of asking users to rate products on, say, a five-star scale, as Netflix and Amazon do, recommendation systems should ask users to compare products in pairs. Stitching the pairwise rankings into a master list, Shah argues, will offer a more accurate representation of consumers’ preferences.

World's data will grow 50 times

2011-07-01T07:22:00.006Z

In 2011 alone, 1.8 zettabytes (or 1.8 trillion gigabytes) of data will be created, the equivalent to every U.S. citizen writing 3 tweets per minute for 26,976 years. And over the next decade, the number of servers managing the world's data stores will grow by ten times.

Interestingly, the amount of data people create by writing email messages, taking photos, and downloading music and movies is minuscule compared to the amount of data being created about them, the EMC-sponsored study found.

The IDC study predicts that overall data will grow by 50 times by 2020, driven in large part by more embedded systems such as sensors in clothing, medical devices and structures like buildings and bridges.

Programming in a post-Basic world

2011-06-29T07:22:00.003Z

For years, the lingua franca for desktop computers was the Beginner's All-purpose Symbolic Instruction Code, a.k.a. BASIC. Essentially every PC had it, and just about anyone could learn to program with it, even in a rudimentary way.

Those days are gone -- Microsoft stopped including Basic with its operating system after Windows 95, a corporate spokesperson confirms. Consequently, today's desktop computers have no built-in general-purpose programming language to entice the curious.

IBM's new future: Quantum computing - Computerworld

2011-06-21T07:22:00.003Z

IBM is marking its 100th anniversary by celebrating its record in technology innovation. It created dynamic RAM, the disk drive and the magnetic strips used on credit cards, among many other inventions. It is one of the most inventive companies in the world.

But the computing industry is moving to a new future as disruptive and as radical as the era that began with the introduction of silicon chips, and that future is quantum computing. These are systems that use the behavior of subatomic particles to conduct calculations now performed with transistors on a chip.

This future may be anywhere from 10 to 20 or more years away. But if the potential of quantum computing is fully realized, it may trigger a development rush in chip and hardware design reminiscent of what Silicon Valley experienced decades ago.

Taking Email Etiquette to the Next Level

2011-06-15T07:22:00.003Z

When working with others in the office, most know it is better to approach a colleague who is relaxed and drinking a cup of coffee versus a frazzled co-worker buried under a pile of paperwork.

Unfortunately, email doesn’t offer users the same social cues – until now.

Georgia Tech Assistant Professor of Computing Eric Gilbert has developed software called courteous.ly, a service that shows current user email loads in real-time.

“I think we’re really good at the etiquette part when we have the cues that allow us to be polite,” said Gilbert, a faculty member in the School of Interactive Computing in the College of Computing. “Courteous.ly helps manage expectations and lets people choose to send mail when it’s best for you.”

Available for download, courteous.ly currently works with Google-based email, such as Gmail, which is used by 160 million people worldwide. Roughly 3 million businesses also use Google-hosted mail. Signing up for courteous.ly is as easy as entering your email address and verifying a few links.

Federations and confederations

2011-06-09T15:55:00.000Z

A federation is a type of sovereign state characterized by a union of partially self-governing states or regions united by a central (federal) government. In a federation, the self-governing status of the component states is typically constitutionally entrenched and may not be altered by a unilateral decision of the central government.

A confederation is an association of sovereign member states that, by treaty, have delegated certain of their competences (or powers) to common institutions, in order to coordinate their policies in a number of areas, without constituting a new state on top of the member states. Under international law a confederation respects the sovereignty of its members and its constituting treaty can only be changed by unanimous agreement.

By definition the difference between a confederation and a federation is that the many memberships of the member states in a confederation are voluntary, while the membership in a federation is not. A confederation is most likely to feature these differences over a federation:
(1) No real direct powers: many confederal decisions are externalised by member-state legislation.
(2) Decisions on day-to-day matters are not taken by simple majority but by special majorities or even by consensus or unanimity (veto for every member).
(3) Changes of the constitution, usually a treaty, require unanimity.
